I had a shiny palisade green suit in the eighties, loved it, my favourite ever was a navy and white one-piece. Would happily wear that one again if they do come back into fashion. Did see several people wearing 'vintage' gear last year. Never sure whether it's deliberate fashion statement, or just that they are too tight to buy a new outfit.
I've found that having a hissy fit at one's other half, halfway down a piste, for being persuaded into trying a baby blue steep black on the first week also seems to draw notice . Particularly when the OH then does a lazy backwards snowplough in front of you the rest of the way so you can't see 'the steep'.
